Definitions

  • the present invention has for its object an extra-thin fluid-fight watch comprising a back-calotte, a middle-bezel and a glass, assembled hermetically, so that the thickness of the watch be minimal, and its fluid-tight packing-ring does not risk deteriorating.
  • This watch is characterized by the fact that the glass has a vertical wall terminated by a heel maintained between the back-calotte and the middle-bezel, the water resistance being assured by a packing-ring disposed around the periphery of the said heel, and level with the heel, the compression of this packing-ring being limited aXially by the thickness of the heel.
  • FIGURE 1 shows a partial section of a circular water resistant watch
  • FIGURE 2 shows a square watch
  • FIGURE 3 shows a partial section of the watch according to FIGURE 2.
  • FIGURE 1 the movement 1 can be seen, surmounted by the dal 2, the assembly being enclosed hermetically in the envelope constituted by the back-calotte 3, the middle-bezel 4 and the glass 5.
  • the glass 5 comprises a cylindrical part 6, termnated by a heel 7 maintained between the back-calotte 3 and the middle-bezel 4, the latter being fixed on the backcalotte 3 by a known bayonet type of looking device 8.
  • the middle-bezel 4 presses the heel 7 against the edge of the back-calotte.
  • the space formed, delimited by the middle-bezel, the back-calotte and the heel 7, is occupied by a packing-ring of water resistance 9 Situated thus at the same level as the heel 7.
  • This fluid- Patentjed Sept. 3,' 1968 tight packing-ring will be submitted to pressures 'limited by the rigid dimensions of its housing.
  • the movement is maintained in place by a shoulder 10 of the glass 5 which bears against the edge of the dal 2.
  • the shoulder 10 could be Situated higher, so that the dal would penetrate more deeply into the cylindrical part of the glass, the thickness of the watch thus being reduced.
  • the shoulder represented can be replaced by a rounded housing or simply by a bevel hearing against the edge of the dal.
  • the case is in the shape of a square.
  • the space left free by the angles of the case permit the movement to be fixed no longer by its dal, but by two screws 11 and 12 whose heads in the shape of a half moon are introduced by an unscrewing movement into a groove 13 formed in the edge of the movement and having a slightly inclined plane.
  • the dal can be engaged more deeply under the glass, further reducing the total thickness of the watch.
  • Shaped watch according to claim 1 wherein said movement has a groove with an inclined plane in the edge thereof and an adjustable securing device mounted on said back-calotte and projecting inwardly to engage said groove in said movement to maintain the same in place.
